[S-TT41] Seismic monitoring and processing system

Fri. May 30, 2025 9:00 AM - 10:30 AM 106 (International Conference Hall, Makuhari Messe)

convener:Yusuke Tomozawa( KAJIMA Corporation), Hisahiko Kubo(National Research Institute for Earth Science and Disaster Resilience), Chairperson:Akito Araya(Earthquake Research Institute, University of Tokyo), Tatsuhiko Hara(International Institute of Seismology and Earthquake Engineering, Building Research Institute)

This session covers scientific and technical issues in seismic monitoring or data processing systems for earthquakes or explosion observation. The topics include developing or improving seismic observation networks, innovative techniques in observation and monitoring, and cutting-edge data acquisition and processing techniques in geophysical explorations. Other topics related to geophysical observation are also welcome.
